Liam Payne has appeared to confirm his romance with Cheryl Fernandez-Versini[Liam Payne/Instagram]

Then Liam changed his Instagram profile picture of the pair together - and everyone knows that when a boy puts a girl in his profile picture it's a sign of pure, unadulterated love.

And it wasn't just any picture. Liam was TOPLESS in the snap while Cheryl was resting her head on his shoulder in a "we really love each other" type pose.

But fans were left confused once again when Liam removed the snap just a day later and reuploaded a snap of him alone.

Fans were quick to speculate that the chap in the snap was Liam.

Cheryl then made things even more confusing when she shared a snap of herself alongside 3 men she's been linked to - L'Oreal manager Adrien Koskas, photographer Mariano Vivanco and the one and only Liam.

She captioned the snap: ""My mystery man line up #whosthemysteryman #whoisit #whosworthit."

Liam then took to his own Instagram account and posted a snap of the pair looking cosy in the back of a car.

We we guessed was his way of saying: "It's me."

BUT THEN...
